Yang Liwei: Take off and experience "darkness" for 26 seconds
I thought I was going to sacrifice
Witnesses say

On October 15, 2003, Chinese astronaut Yang Liwei successfully traveled back and forth between heaven and earth in the Shenzhou V spacecraft.
He is the first generation of astronauts trained by our country. He was 38 years old when he was flying.
Behind his heroic deeds, there is a little-known 26 seconds.
At 9 o'clock on October 15, 2003, the Shenzhou V spacecraft lifted off, and the raging flames pierced the sky.
In the eyes of the ground personnel, the launch went smoothly, but Yang Liwei felt the imminent death.
When the rocket rose to an altitude of thirty or forty kilometers, it suddenly resonated strongly with the spacecraft. Everything in the cabin, including himself, began to vibrate sharply. What's more frightening was that the vibration was superimposed with a load of 8 G, and he felt it before his eyes. It was pitch black, and the internal organs seemed to be shattered.
This was something Yang Liwei had never experienced in hundreds of training sessions on the ground. He once thought he was going to sacrifice.
"Hold on, hold on again." Yang Liwei gritted his teeth.
Resonance seems to be testing the first visitor from China in space.
Fortunately, the discomfort quickly eased.
The journey to the sky is difficult and dangerous. Many unpredictable factors cannot be fully simulated by the ground, and low-frequency resonance is one of them.
The low-frequency vibrations in the spacecraft cabin below 10 Hz will vigorously resonate with human internal organs, directly threatening the safety of astronauts.
Although the researchers expected and dealt with it accordingly, what Yang Liwei experienced was something they did not expect.
The resonance lasted for 26 seconds.
So short and so long.
It came aggressively, but it did not stop the Chinese astronauts from conquering space.
Deng Yibing, director of the Astronaut Scientific Research and Training Center, once commented: 26 seconds is a microcosm of the difficulties and obstacles of China's first manned space flight, demonstrating the bravery and loyalty of Chinese astronauts.
As the pioneers of manned space engineering, astronauts must be prepared to give their lives at any time in addition to earnestly training and completing missions.
On September 25, 2008, Chinese astronauts Zhai Zhigang, Liu Boming, and Jing Haipeng took the Shenzhou VII spacecraft and embarked on a flying journey.
They spent nearly two days completing the preparations in orbit. On September 27, Zhai Zhigang opened the spacecraft door and took the first step of the Chinese in space, becoming the 354th astronaut in the world to walk out of the capsule.
Suddenly, a rapid alarm sounded in the orbital module: "The orbital module is on fire! The orbital module is on fire!" Zhai Zhigang recalled afterwards, feeling that his hair suddenly stood up.
Jing Haipeng, who was on duty in the return cabin, inspected the system, judged the problem with Liu Boming, and sent a report to the ground at the same time.
Liu Boming couldn't figure out the situation for a while, but he made a decision.
According to the plan, Zhai Zhigang would first retrieve a space science experiment sample fixed outside the cabin after leaving the cabin, but Liu Boming adjusted the steps and directly handed the national flag out.
Through television signals, audiences all over the world witnessed the five-star red flag embroidered by scientific and technological personnel flying in space.
It was confirmed that this was just a false alarm.
After returning, the three astronauts expressed their thoughts at the time: "If you can't come back, take the picture of dancing the national flag as our farewell."
